Tesla MODEL S Operating Manual page 94

To resume cruising at the current driving
speed, move the cruise control lever up or
down, then release.
Note: When Traffic-Aware Cruise Control
cancels, Model S does not coast. Instead,
regenerative braking slows down Model S in
the same way as when you move your foot off
the accelerator when driving without Traffic-
Aware Cruise Control (see
Braking on page 67).
Warning: Traffic-Aware Cruise Control
cancels, or may not be available, in the
following situations:
• You press the brake pedal.
• Your driving speed exceeds the
maximum cruising speed of 90 mph
(150 km/h).
• You shift Model S into a different
gear.
• A door is opened.
• The view from the radar sensor or
camera(s) is obstructed. This could
be caused by dirt, mud, ice, snow, fog,
etc.
• The traction control setting is
manually disabled or is repeatedly
engaging to prevent wheels from
slipping.
• The wheels are spinning while at a
standstill.

• The Traffic-Aware Cruise Control
system is failing or requires service.
When Traffic-Aware Cruise Control is
unavailable or cancels, Model S no longer
drives consistently at a set speed and no
longer maintains a specified distance
from the vehicle ahead.
Warning: Traffic-Aware Cruise Control can
cancel unexpectedly at any time for
unforeseen reasons. Always watch the
road in front of you and stay prepared to
take appropriate action. It is the driver's
responsibility to be in control of Model S
at all times.
Summary of Cruise Indicators
Traffic-Aware Cruise Control is
available but is not actively
controlling your speed until you
activate it. The number shown in
gray is determined by Speed Assist
(see Controlling Speed Assist
page 116).
Traffic-Aware Cruise Control is
operating and is either maintaining
the set speed (no vehicle in front) or
is maintaining a chosen following
distance from a vehicle ahead (up to
the set speed).
Model S has fully stopped but is in a
HOLD state. If safe, press the
accelerator pedal to resume cruising
at the set speed.
Limitations
Traffic-Aware Cruise Control is particularly
unlikely to operate as intended in the
following types of situations:
• The road has sharp curves.
• Visibility is poor (due to heavy rain, snow,
fog, etc.).
• Bright light (such as from oncoming
headlights or direct sunlight) is interfering
with the view of the camera(s).
• The radar sensor is obstructed (dirty,
covered, etc.).
• The windshield is obstructing the view of
the camera(s) (fogged over, dirty, covered
by a sticker, etc.).
